Primary data for article: Lundgren, Lázaro and Totland "Effects of experimentally simulated pollinator decline on recruitment in two European herbs". Accepted in Journal of Ecology in January 2015. Here we used a novel experimental approach that simulates pollinator decline to assess the effects of a 4-year reduction in pollinator availability on reproduction and recruitment in two common European herbs, Centaurea jacea and Leucanthemum vulgare. Our experiment reduced pollinator availability without artificially affecting quality components of the pollination process. Therefore, this approach may represent a realistic simulation of a pollinator decline. To our knowledge, this is the first study that uses an experimental reduction in pollinator visitation to assess its effects on population recruitment in plants. This study shows that a large pollinator decline may affect population densities, but only in populations where seedling recruitment is limited by seed production. Our results also highlight the importance of going beyond visitation rates and seed production to study the impact of pollinator decline on plant populations.

本研究的原始数据源自Lundgren、Lázaro与Totland于2015年1月被《Journal of Ecology》接收的论文《Effects of experimentally simulated pollinator decline on recruitment in two European herbs》。本研究采用一种全新的实验方法模拟传粉者衰退（pollinator decline），以评估传粉者可及性（pollinator availability）连续4年下降对两种常见欧洲草本植物——矢车菊（Centaurea jacea）和滨菊（Leucanthemum vulgare）——的繁殖与种群补充（recruitment）的影响。本实验在未人为干扰传粉过程（pollination process）各项质量参数的前提下降低了传粉者可及性，因此该方法可较为真实地模拟传粉者衰退场景。据我们所知，本研究是首个通过实验降低传粉者访花（pollinator visitation）频率，以评估其对植物种群补充影响的研究。研究结果表明，传粉者大幅衰退可能会影响种群密度，但该效应仅在幼苗补充（seedling recruitment）受种子生产限制的种群中显现。本研究结果同时强调，若要探究传粉者衰退对植物种群的影响，需超越传粉者访花率与种子生产的研究范畴。
